Axiom pioneered the use of DSP for subwoofer amplifiers many years ago. Competitors are now trying to implement it in their products; playing the catch up game.

The hardware for the DSP is easy to find but the software needed to allow the DSP technology to improve the overall performanec of the subwoofer is a diffrent story. Axiom has created its software and has been refining it for many years. It takes a lot of scientific research and extentive testing requiring uniqe skill, know how, elaborate equipment and more. Not many companies, including subwoofer companies, posses and master them as Axiom does.

Thanks for the explanation! I just know that it sounds great in my EP600.
